Overexcitabilities are sometimes used to help predict "giftedness" in both children and adults: The more "excited" or the more stimulated a sense is in a person, the more susceptible or prone their brain is to react in an extreme manner to anything that triggers it, thus the possibilities of expansion in ways of learning are increased in this person. Gifted people appear to be very in touch with their 5 senses possibly making them, in a sense, more 'global' than others.
